Rowan to Build Two New LeTourneau 240C Jackup Rigs

Rowan Companies announced plans for the construction of two jack-up
rigs to add to its offshore fleet. The rigs will be a new design
called the LeTourneau 240C. This design has enhanced environmental and
drilling capabilities to meet the ever increasing operational
requirements of worldwide exploration and production. Each rig will
cost approximately $165 million and will be constructed at Rowan's
Vicksburg, Mississippi facility. Expected delivery of the first rig is
early summer 2008, and the second in early 2009. Rowan currently
anticipates funding construction with available cash, but will
consider attractive financing alternatives.

The 240C rigs will have up to 535 feet of leg length, enabling
operations in water depths of up to 400 feet, and are designed for
high pressure/high temperature drilling. Compared to the 116C design,
the 240C rigs will have more deck space, higher variable load, more
drilling capacity (two million pound hook-load capability), more
cantilever reach (up to 85 feet) and increased personnel on board (120
man). The 240C design will set a new standard as a replacement for the
industry's current fleet of 116C rigs, which has been the "workhorse"
of the global drilling industry for the past 25 years.

Danny McNease, Chairman and Chief Executive Officer, commented,
"The construction of these rigs, utilizing the resources of our
manufacturing division, will accelerate the process of replacing our
rigs lost in the recent hurricanes, and will further enhance our fleet
of technically superior jack-up drilling rigs operating in niche
markets. The construction of the two 240C rigs, together with the
previously announced Hank Boswell and Tarzan IV, will provide us with
rig deliveries in each of 2006, 2007, 2008 and 2009. By summer 2006,
we will also have nine new land rigs working under term contracts at
very attractive day rates. This expansion and acceleration of our
construction program will greatly enhance our asset and revenue base
and further strengthen our market position."
